Description

About as realistic as you can get when it comes to 1911 air guns. The slide moves just as it would in a firearm. The air pistol is even better than the firearm -- because you get 20 shots from a mag!

We put together this kit so you have everything you need the minute your package arrives. You can start shooting right away.

If you like the 1911 frame and can't get to the range to practice with your firearm, this gun will go a long way toward helping you maintain proficiency. You'll also save a lot of money by shooting steel BBs instead of live ammo.

Steel BBs can ricochet. The shooter and everyone in the shooting area should wear safety glasses when a gun is being handled (even if it's unloaded). Remember to remove all pets from the area, as rebounding ammo can hit them, too. Never shoot steel BBs at hard objects (including metal targets) or water, as that increases the chance of ricochet.

Weight and size of grip are ok. nice blow back. with a laser attached and the fake silencer attached make it appear really cool. ive had no issues with removing the co2 cartridge like others have mentioned.

cheap plastic handle does ruin the over all quality of the gun. does not always lock back after final shot. first round of 10 pellets it locked back. next 40 shot it would not lock back nor would it lock after cocking by hand. last 40 shots it would lock. go figure!! paint on rail guide wore off after 1st co2 cartridge.

be warned, after owning a 1911 we the people and a spartan 1911, this gun feels light and cheap. sad, as this is only 20 cheaper than the we the people and the spartan. spend the extra and get one of those or a swiss arms 1911. sad, as this is my 2nd and possibly last asg made gun.

Hi I just got home a couple hours ago to find my new STI Duty One by ASG. My second ASG product in a week! Ha.. My first is was the CZ 75 PO7 Duty..I fell in love.. I had to get another to add to my collection and I ordered the kit and the larger frame pistol in the 45 acp format. I've already used up one CO2 in the basement range and I'm very very happy. Great weight snappy blowback solid and 80 full power shots with one CO2.. Very accurate with the laser ..

I think it's just a little light in the grip even loaded. The door that opens up to instal the CO2 should be metal not that the plastic one is cheap but to add grip weight.. Just a little.And I would like to see white or some highlighting on the sights. I may paint my muzzle sight white.

I only just got this gun literally.. I'm writing this down literally just after firing its first CO2 and I'm so far impressed. I have big hands and the full size frames really help. I will do another review after I fire this awesome great looking 45.or after I've owned it longer I hope I don't jinx myself it did seam a little dry so I did lightly P ellgun oil the trigger. I've had dry Hatsan rifles before so maybe I'm being paranoid but a little Pellgun oil can't ever hurt.. I will b very thorough with my next review after using it more but those 80 rounds were smooth and impressive definitely in the high 300's or close to 400 fps..

Looks. Weight, nice report when fired and like slide recoil. Rear sight is adjustable for wind age.

Threaded fake silencer should be a barrel extension and not a hollow tube. This would aid accuracy.

The front sight is so tall, it shoots very low even at 20 feet. With 220 black sandpaper Around a flat file, I reduced the height by one half. Then put a dot of white paint on it to improve the sight picture. The slide will lock to the rear when empty only now and then. Haven't figured that one out yet. It maybe a weak spring that moves the slide lock upward. Then as others have noted the empty co2 powerlet does not come out of the grip easily. I use a small magnet to help it out. Some other suggestions are tie a string or ribbon to it.

My rear sight is held on by a small Allen head and that size Allen wrench came with the kit.But the sight isn't adjustable but removable.Maybe look for a trueglow or different sight? But no adjustment definitely I'm looking at it now.. But easy to upgrade.

Unfortunately the fake slencer does not work with the model shown as the model shown DOES NOT HAVE A THREADED BARREL. The box that was sent showed the upgraded model WHICH IS THREADED but the lower end model...shown in this picture - was in the box. YES...they did refund the ENTIRE purchase price and shipping and also paid for all return shipping. Still....very disappointed.

Pyramyd Air should remove this ad and replace it with the model that has the threaded barrel to accept the fake silencer.

See Above

The threaded muzzle is fantastic.. Its nice being able to use what came with the Duty One kit with my other ASG pistols The suppressor fits the CZ75 P07 duty the Bersa its cool switching up.My first threaded barrel and suppressor and although fake it is very cool and a 177 is quiet anyways.. Pretend the suppressor does it..lol

Hi I have this pistol in airsoft version and have the Bersa bb9cc b.b versions both black and 2 tone I also have the A.S.G. cz 75 po7 in 4.5.mm. steel b.b. version and the mock silencers work on every one of my guns after removing the muzzel thread gaurd with the supplied key. Thanks Kevin

Appreciate your input and now the picture instruction on the ad - EXCELLENT. WIth that...am going to purchase this product again.

Edith Nov 05, 2014

There's a small black tool included with this kit. You insert it into the muzzle and turn it to loosen the piece that covers the threads. Once that piece is removed, you can easily screw in the fake silencer. Apparently, this is a common way of protecting the threads and is well known by airsoft buyers. However, it's not well known among airgunners. We'll update our photos to show the tool and how it's used. I appreciate your bringing this to our attention!
